Executed during Pâris' first stay in Rome (1771-1774), when he was a pensionnaire at the Académie de France then located at the Palazzo Mancini on the Corso. Pâris' interest in the decorative patterns and arabesques of the Raphael Loggie in the Vatican is well documented (see Giovanni Volpato. Les loges de Raphaël et la galerie du Palais Farnèse, exhib. cat., Tours, Musée des Beaux-Arts, 2007, pp. 202-203). He frequently visited them, described drawing them in his journal, and accompanied French visitors there during their stay in the city. One such visitor was the influential fermier général Jacques-Onésyme Bergeret de Grancourt (1715-1785), whom he accompanied to the Vatican in 1773. Drawings similar to this one, after the grotesques on the pilasters in the Loggie, are bound in albums now in the Musée des Beaux-Arts, Besançon (ibidem, nos. 52 and 53).
This sheet may belong to a group of drawings that Pâris sent to the Académie de France in Paris to justify his activity abroad, as it is recorded in his diary ('Listes des études que j'envoye à Paris', ibidem, p.203, n. 12).
Presumably the artist enjoyed the combination of his name and 'Romae' in his signature.
